Also known as Zykadia, Ceritinib is indicated for the treatment of non-small cell lung cancer (NSCLC), which in turn happens to be the most common type of lung cancer. According to medlineplus.com, this medication works “by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.” Remember to let your doctor know about your other medical conditions before using Ceritinib- particularly if you have heart problems, low levels of potassium/magnesium in your blood, a pancreas disorder or if you are diabetic. Bear in mind that pregnancy while taking Ceritinib is not recommended, considering this drug can harm an unborn baby. Therefore, it is important for both men and women to prevent pregnancy through effective birth control methods (condoms, pills and whatnot). According to drugs.com, the side effects of Ceritinib can range from mild, such as stomach pain, loss of appetite, nausea, vomiting and diarrhea, to life-threatening (e.g. high blood sugar, liver problems, shortness of breath, and sudden dizziness). So, if you have any of the latter effects, call your doctor immediately. On a side note, Ceritinib capsules should be taken once per day, preferably with food.
